Description

Technical Field

[0001] The utility model relates to the technical field of field bridge maintenance, in particular to a field bridge trolley mechanism disassembly device. Background Art

[0002] The trolley mechanism of the field crane is a frequently working mechanism, and its reliability and safety are self-evidently important. The field crane trolley mechanism reducer, motor, drive shaft, wheels, etc., as important components of the field crane, directly affect the working efficiency of the crane. Under normal operating conditions, the failure rate of the trolley mechanism accounts for 20% to 40% of all failures. Strengthening the maintenance and repair of the field crane trolley mechanism is an important means to reduce the failure rate of the trolley mechanism and reduce trolley safety accidents. The frequency of disassembly and replacement of the field crane trolley mechanism parts by engineering and technical personnel is fast, the number is large, and the workload is large, which has become an important part of the maintenance of lifting equipment. However, the field crane trolley mechanism reducer, motor, drive shaft, wheels, etc. are each 200KG-500KG, which is very difficult to carry by manpower.

[0003] Due to the limited maintenance range of the crane, the maintenance and replacement of the reducer, motor, drive shaft and wheel of the crane trolley mechanism currently requires the cooperation of a truck crane for lifting. Every time maintenance needs to be done, a truck crane must be asked to assist in lifting, and the maintenance time must also be based on the arrival time of the truck crane, which greatly affects work efficiency.
